PY-E509 Muffle Furnace, also known as chamber resistance furnace, paper raw materials, pulp, paper and cardboard Ash Tester Fibrous Row Material Pulp **and Board---Ash Tester. Muffle means wrap, and furnace means furnace, furnace. The common names of muffle furnace in China are as follows: electric furnace, resistance furnace, Maofu furnace, and Mafu furnace. The muffle furnace is a kind of general heating equipment, which can be divided into box furnace, tube furnace and crucible furnace according to the appearance and shape.

Box resistance furnace PY-E509 muffle furnace is a common form of electric furnace, which is divided into vertical, horizontal, split and integrated type. The temperature section is divided into below 1200 degrees, 1400 degrees, 1600 degrees, 1700 degrees, 1800 degrees, etc., respectively, with resistance wire, silicon carbon rod, silicon molybdenum rod as heating elements, according to the needs can be selected, in addition to the usual heating in the air, the box-type electric furnace also has a breathable atmosphere and a sealed vacuum electric furnace, various forms. It is widely used in the production and experiment of ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new material development, special materials, building materials and other fields.

The classification of muffle furnaces can be based on their heating elements, temperature ratings, and controllers, as described below

1) According to the heating elements, there are: electric furnace silk muffle furnace, silicon carbon rod muffle furnace, silicon molybdenum rod muffle furnace;

2) According to the rated temperature, it is generally divided into: 1000 muffle furnace muffle furnace muffle furnace muffle furnace muffle furnace. 1800 muffle furnace.

3) According to the controller, there are the following types: pointer table, ordinary digital display table, PID adjustment control table, program control table;According to the insulation material, there are two kinds: ordinary refractory bricks and ceramic fibers.

1. The appearance is treated with high-temperature resistant and corrosion-resistant paint.

2. The console adopts intelligent PID digital display controller, which has good stability, high precision, is equipped with an ammeter and has a novel structure.

3. The furnace door is thickened and reinforced to prevent deformation.

4. The furnace lining is made of high-quality insulation cotton, which has good insulation effect.

5. The furnace temperature is detected from time to time (the actual temperature of the furnace is also displayed when it is not heated, which is convenient for observing the furnace temperature at any time).

6. The wiring is simple, the diagram is clear, and the operation is convenient.

7. It has overload protection and short-circuit protection.

8. The furnace shell is made of high-quality steel plate folding and welding, the studio is a furnace made of refractory materials, the heating element is placed in it, and the furnace and the shell are masonry with thermal insulation materials.

1000°c

Applicable temperature

The rated temperature of the box-type resistance furnace PY-E509 muffle furnace is 1000-1700, which is suitable for the sintering of metal materials and ceramic materials, the heat treatment of some single crystals, and the detection and research of high-temperature reburning and shrinkage of refractory materials.

Maintenance

1. The controller should be placed in a dry and well-ventilated place without corrosive gas, the working environment temperature is -10-50, and the relative humidity is not more than 85%.

2. In order to ensure the accuracy of the measurement, the DC potential difference meter should be used to calibrate the thermometer of the XMT type temperature controller every year to avoid causing large errors.

3. Regularly check whether the wiring of each part is loose and whether the contacts of the AC contactor are good. If there is a fault, it should be repaired in time.

1) Thermal processing, industrial workpiece processing, cement, building materials industry, thermal processing or treatment of small workpieces.

2) Pharmaceutical industry: used for drug inspection, pretreatment of medical samples, etc.

3) Analytical chemistry industry: as sample processing in the fields of water quality analysis and environmental analysis. It can also be used to carry out petroleum and its analysis.

4) Coal quality analysis: used to determine moisture, ash, volatile matter, ash melting point analysis, ash composition analysis, element analysis. It can also be used as a general purpose ashing furnace.
